Love, Love Medulla: The Neuroscience of Beatlemania

The term “Beatlemania” has come to be associated with many things over the past half-century.

Coined in October 1963 during the Beatles’ tour of Scotland, the extent of Beatlemania in the United States is obvious by record sales alone. Between the 1964 release of “I Want to Hold Your Hand” on the Billboard Hot 100 and the Let it Be EP in 1970, the Lads from Liverpool had a Number One single for, on average, one out of every six weeks, and the top-selling album once every three weeks.

But to most, “Beatlemania” incites a vivid image of frenzied fans, predominantly teenage girls, looking as though they’ve just witnessed a gruesome murder. Fat buttons proclaiming “I LOVE GEORGE” adorn cardigan sweaters, hanging on for dear life as their owners attempt to push past overwhelmed human police barricades. Nurses stand at the ready, armed with smelling salts and ready to rouse the next fainting victim. Lots of tears. Lots of screaming.

As we approach the 50th anniversary of John, Paul, George, and Ringo’s first U.S. appearance on The Ed Sullivan Show this Sunday, we can’t help but look back and laugh nostalgically. Just what was it about the moptop haircuts, Cuban heels, and “yeah yeah yeah”s that turned us, our parents, or our grandparents into primeval beings whose sole purpose was to drown out the blare of a Vox AC30 amplifier?

As it turns out, neuroscience can (partially) explain the phenomenon.

Why do we cry when we're happy?

It's been awhile, braniacs. But I have an excuse! A good one, I swear!

I got married to the love of my life on August 10—who I, of course, met in a neuroscience lab a few years ago.

Something inexplicable has been plaguing me the past few months, though. Getting married, including the months of stressful planning and nightmares leading up to the big day, was the happiest time of my life.

I reveled in choosing dresses and shoes, booking vendors, and constructing centerpieces. I saw my family and friends a lot over the past few months. And, after all, I was celebrating one of the purest and most joyful things that can be celebrated in this crazy, mixed-up world: love.

But, for some reason, I found myself crying a lot more. Not out of sadness or frustration or hopelessness, though.

I mean, I couldn't even keep it together while walking down the aisle—something every girl, growing up, likes to daydream about...right? (See pathetic photo.)

Most of us have heard that crying, in essence, is good for us—that it relieves us when we're sad, releases stress and toxins, yadda yadda.

So what was with my sobbing on what was inarguably the happiest day of my life?

Fainting at the sight of blood

I remember the day so well because the circumstances were so ridiculous.

It was my freshman year of high school, the Friday before homecoming weekend. Football players and cheerleaders wore their respective uniforms to class, I had a blue pawprint painted on my face, and everyone in class was antsy in anticipation of the pep rally at the end of the day.

Our health teacher put on some Red Cross first aid video to appease our restlessness. Halfway through the video, an actor began "bleeding" profusely from the arm. Just as his friend ripped off a bit of his t-shirt to staunch the blood, I saw a flash of blue jersey out of the corner of my eye.

One of the star football players in my class—a pretty massive beast of a human being—slumped down his chair then lay flat on the floor. He was passed out cold.

Do you get woozy when you see blood? It seems like an oddly dramatic physiological response for just seeing a little red liquid, right? As it turns out, fainting at the sight of blood may be a primitive reflex buried deep in our brain.
